Abstract Aegilops tauschii , the diploid wild progenitor of D subgenome bread wheat, is a reservoir genetic diversity for improving wheat performance and environmental resilience. Here we sequenced 242 Ae. accessions compared them to characterize genomic diversity. We found that rare lineage geographically restricted present-day Georgia contributed in independent hybridizations gave rise modern wheat. Through k -mer-based association mapping, identified discrete regions with candidate genes...
Abstract Aegilops tauschii, the diploid wild progenitor of D-subgenome bread wheat, constitutes a reservoir genetic diversity for improving wheat performance and environmental resilience. To better define understand this diversity, we sequenced 242 Ae. tauschii accessions compared them to D-subgenome. We characterized rare, geographically-restricted lineage discovered that it contributed D-subgenome, thereby elucidating origin from at least two independent hybridizations. then used k...
